Transient Elastography (TE) gives a quantitative one-dimensional (i.e. a line) measure of tissue stiffness. It functions by vibrating the skin with a motor to create a passing distortion in the tissue (a shear wave) and imaging the motion or propagation of that distortion as it passes deep into the body using a one-dimensional ultrasound beam. It then displays a quantitative image of tissue stiffness data, as well as the Young's modulus.


• Transient Elastography (TE) technique relies on a transient mechanical vibration which is used to induce a shear wave into the tissue. The propagation of the shear wave is tracked using ultrasound in order to assess the shear wave speed from which the Young’s modulus is deduced under the hypothesis of homogeneity, isotropy, infinite and pure elasticity (E=3ρV²).


• Transient Elastography (TE) is a non-invasive liver detection technology, which can be used to assess the degree of liver fibrosis by Liver Stiffness Measurement (LSM). Due to the advantage of being non-invasive, simple, rapid, easy to perform, reproducible, safe, and well-tolerated, TE has been recommended and recognized by major clinical guidelines and consensus, including the EASL, AASLD, APASL, CMA, and WHO.
